Pomum produces wines from Columbia Valley, Washington's expansive growing region. The winery works with Cabernet Sauvignon, Cabernet Franc, Chardonnay, and Riesling—grapes that thrive in the region's continental climate and volcanic soils. The Shya Cabernet Sauvignon, a Cabernet Sauvignon and Cabernet Franc blend, represents the winery's work with the region's signature red varieties. A Chardonnay and Upland Vineyard Riesling round out the portfolio, reflecting the diversity of Columbia Valley's terroir. Wine Enthusiast and Wine Advocate have rated Pomum's releases.
